This Spinner P3-620 is a used machining center — also commonly referred to as a machining centre or CNC machining center — built in 2011 and currently located in Germany. Machining centers are multi-axis CNC machine tools designed to perform milling, drilling, boring, and tapping operations on metal and other materials in a single setup, and are central to precision manufacturing across the engineering, automotive, aerospace, and general metalworking industries. Spinner is a well-regarded German machine tool manufacturer known for producing high-quality CNC turning and milling machines built to demanding industrial standards.
A particularly notable aspect of this machine is its exceptionally low recorded usage: just 203 spindle hours, which for a 2011 machine suggests it has seen very light service and is reported to be in very good condition. The machine is equipped with a Siemens 840D-SL control system running ShopMill Operate, a widely used and respected CNC platform that supports conversational and ISO programming and is familiar to operators across European manufacturing environments.
The spindle runs at up to 12,000 rpm and accepts SK 40 toolholders, a standard taper widely supported by tooling suppliers. The working envelope covers 620 mm in X, 520 mm in Y, and 460 mm in Z, with a table measuring 1,100 × 560 mm. A 32-pocket chain-type automatic tool changer with a double-arm head enables fast, uninterrupted tool changes during operation.
The machine features an internal two-fold pallet changer operating on a 180-degree rotation, allowing an operator to load and unload workpieces on one pallet while machining continues on the other — a significant productivity advantage that reduces idle time between parts.
Ancillary equipment included with the machine comprises a chip conveyor in the milling area, a scraper belt chip conveyor with integrated coolant system, a belt filter system with through-tool coolant at 40 bar, a hydraulic oil cooling system, machine lighting, and a rotary feedthrough in the table, which supports the connection of pneumatic or hydraulic fixtures on the pallet.
